Description

  The present invention relates to a fixture support structure and fixture.

  In various facilities such as offices, public facilities, educational facilities, commercial facilities, hospitals and the like, furniture with a top plate such as a so-called desk device is widely used for various purposes including meetings and meetings. As such a fixture with a top plate, there is known a device provided with a movement restraint mechanism that restricts the movement of the fixture in use, and releases the constraint and allows the movement by a caster to change the arrangement of the fixture. It has been.

  For example, the table described in Patent Document 1 includes a base provided on the floor, a pedestal standing upright from the base, and a top plate rotatably supported by the pedestal, and the base is used. A person has been proposed that includes a caster that extends in the front-rear direction facing the table and is provided on both sides in the front-rear direction, and a rocking body that is provided on one side in the front-rear direction. The oscillating body is connected to the top plate and an operation lever provided on the top plate by a release wire, and the oscillating body rotates about a shaft member that faces in the horizontal direction by the rotation of the top plate or the lever operation, and the oscillating body A stopper provided at the lower end of the moving body is configured to contact the floor surface.

Japanese Patent No. 5192801

  However, in a fixture such as a table described in Patent Document 1 described above, since the horizontal movement is restricted by the frictional force generated between the ground surface of the stopper and the floor surface, the frictional force is ineffective. If it is enough, the fixture may move on the floor. Further, if the oscillator further rotates around the shaft member from the position where the stopper contacts the floor surface, the contact surface may move away from the floor surface, and movement may not be restricted.

  This invention is made | formed in view of the said situation, and provides the support structure body and fixture of a fixture which can raise braking force so that it may not move along the floor surface of a fixture.

In order to solve the above problems, the present invention employs the following means.
That is, the support structure of the fixture according to the present invention is provided on the support leg installed on the floor, the caster provided on the support leg and movable on the floor, and provided on the support leg. A support shaft extending in the horizontal direction, and a grounding member that is rotatably provided on the support shaft and rotates from a separated position where the grounding surface is separated from the floor surface to a grounding position where the grounding surface is grounded to the floor surface And in a state where the grounding member is grounded to the floor surface, from the rear end portion in the rotation direction from the separated position to the grounding position on the grounding surface of the grounding member grounded to the floor surface. The distance to the shaft center of the support shaft is longer than the distance from the front end portion of the ground contact surface of the ground member in the rotation direction to the shaft center of the support shaft.

  In the fixture support structure configured as described above, the distance from the rear end in the rotation direction of the ground plane to the axis of the support shaft is the distance from the front end in the rotation direction of the ground plane to the support shaft. Longer than the distance to the axis. For this reason, if a force is applied to the fixture support structure and the grounding member is further grounded around the support shaft from the state where the grounding member is grounded on the floor surface, Since the rear end portion in the moving direction presses the floor surface, the braking force can be increased so that the support structure of the fixture does not move along the floor surface.

  Further, in the fixture support structure according to the present invention, the grounding member is provided with a crossing surface intersecting the grounding surface at an end of the grounding surface at the rear in the rotation direction, It is preferable to intersect at the rear end so as to form an acute angle with the intersecting surface.

  In the fixture support structure configured as described above, an intersection surface that intersects the grounding surface at an acute angle is provided at the rear end in the rotational direction of the grounding surface. Therefore, when the grounding member is further rotated forward in the rotational direction around the support shaft from the state where the grounding member is grounded to the floor surface, the rear end in the rotational direction formed at an acute angle. Since the portion comes to abut against the floor surface at an acute tip, the braking force can be further increased so that the support structure of the fixture does not move along the floor surface.

  In the fixture support structure according to the present invention, the grounding surface of the grounding member may be formed in a planar shape.

  In the fixture support structure configured as described above, since the grounding surface of the grounding member is formed in a flat shape, a large grounding area with the floor surface can be secured, and the frictional force with the floor surface can be increased. .

  Further, a fixture according to the present invention includes the fixture support structure according to any one of the above, and a support member having an upper surface supported by the support leg and capable of supporting an object. To do.

  In the fixture configured as described above, the braking force can be increased so as not to move along the floor surface of the support leg that supports the support member having the upper surface capable of supporting the object.

  According to the fixture support structure and fixture according to the present invention, the braking force can be increased so as not to move along the floor surface of the fixture.

  A main cable 8, a linkage cable 9, and a cable operation member 35 are provided as operation units for operating the rear caster unit 4 and the front stopper unit 7 as described above.

  As shown in FIG. 1, the main cable 8 is locked to the lower surface of the top plate 3 or the like. The main cable 8 is inserted through a cylindrical guide sleeve 91 provided inside the support column 20 of the support leg 1. As shown in FIG. 3, the lower end portion of the guide sleeve 91 is held in a state in which downward movement is restricted by abutting against a sleeve holding portion 19 formed in the upper frame 11. The sleeve holding portion 19 is formed with an insertion hole 19h through which the main cable 8 led downward from the lower end portion of the guide sleeve 91 is inserted.

As shown in FIG. 1, the cable operation member 35 is provided on the lower surface of the front end portion 3 f of the top plate 3.
The cable operating member 35 is integrally provided with a base portion 36 supported so as to be rotatable about an axis orthogonal to the lower surface of the top plate 3 and a lever portion 37 extending from the base portion 36 to the outer peripheral side. An upper end portion of the main cable 8 is locked to the base portion 36.
In the present embodiment, the second linkage member 66, the linkage cable 9, and the third support shaft S3 constitute the linkage mechanism 102.

Next, operations of the rear caster unit 4 and the front stopper unit 7 when the top 3 is changed from the use state to the non-use state will be described.
As shown in FIGS. 1, 3, and 4, when the top surface 3 a of the top plate 3 is in a horizontal plane, the lower end portion of the rear cover portion 16 and the ground contact surface 73 of the front stopper 72 are the floor surface F. Is grounded. The rear casters 43 are spaced apart (floating) upward from the floor surface F, and the front casters 79 are grounded to the floor surface F. As a result, the weight of the desk device 100 acts on the rear cover portion 16 and the front stopper 72 provided on each of the pair of support legs 1 and restrains the horizontal movement of the desk device 100 on the floor surface F. .

  In this use state, the main cable 8 is pushed down, and the slide shaft T provided in the second linkage member 66 hits the rear end 41b of the guide groove 41h provided in the swing member 40. ing.

  In order to move the desk device 100, first, the lock lever is unlocked, and the front end 3f of the top plate 3 is pulled upward. Then, the top plate 3 rotates around the shaft 22. As shown in FIG. 5, this causes the main cable 8 provided on the lower surface of the top plate 3 to move upward together with the top plate 3. When the main cable 8 is pulled upward, the second linkage member 66 to which the lower end tie 83 of the main cable 8 is locked is pulled forward. The slide shaft T provided on the second linkage member 66 moves to the front end 41f side along the guide groove 41h of the swing member 40. The first series engaging member 61 through which the slide shaft T is inserted rotates around the second support shaft S2. Since the first engaging member 61 rotates to lower the lower end position downward, the swing member 40 swings so that the rear end portion is pushed downward. As a result, the rear casters 43 provided on the swing member 40 are grounded to the floor surface F. The rear cover portion 16 is displaced upward from the floor surface F relative to the rear caster 43.

As the second linkage member 66 moves forward, the linkage cable 9 connected to the second linkage member 66 is pulled backward, and as shown in FIG. 6, the front stopper 72 moves the third support shaft S3. The grounding surface 73 is rotated about the center so as to face upward and forward. The ground contact surface 73 of the front stopper 72 is spaced upward from the floor surface F.
As a result, only the front casters 79 and the rear casters 43 are grounded to the floor surface F, and the desk device 100 is released from the restraint so that it can travel on the floor surface F.

Further, in order to ground the front caster 79 and the rear caster 43 to the floor surface F as described above, the lever 37 of the cable operation member 35 is operated while the upper surface 3a of the top plate 3 is kept horizontal to operate the cable. The member 35 can also be rotated. Then, the main cable 8 locked to the base portion 36 of the cable operation member 35 is pulled forward, and the main cable 8 in the support column 20 is pulled upward. Similarly to the above, the front caster 79 and the rear caster 43 are grounded to the floor surface F. Even in this case, only the front caster 79 and the rear caster 43 are grounded to the floor surface F, and the desk device 100 is released from the restraint. Thus, the vehicle can travel and move on the floor surface F.

  In the desk device 100 configured as described above, the distance T1 from the front end portion 73f of the ground surface 73 to the axis X3 of the third support shaft S3 is the axis of the third support shaft S3 from the rear end portion 73b of the ground surface 73. It is longer than the distance T2 to the heart X3. For this reason, a force is applied to the desk device 100, and the front stopper 72 is further rotated forward in the rotation direction around the third support shaft S3 from the state where the front stopper 72 is in contact with the floor surface F. In this case, the front end portion 73f presses the floor surface F, so that the braking force can be increased so that the desk device 100 does not move along the floor surface F.

  Further, a first inclined surface 74 that intersects with the ground contact surface 73 at an acute angle is provided at the front end portion 73 f of the ground contact surface 73. Therefore, when the front stopper 72 is further rotated forward about the third support shaft S3 from the state in which the front stopper 72 is in contact with the floor surface F, an acute angle is formed. Since the front end portion 73f comes to abut against the floor surface at an acute angle tip, the braking force can be further increased so that the desk device 100 does not move along the floor surface F. In particular, when the floor surface F is formed of a fibrous material such as carpet or carpet, the front end portion 73F is likely to pierce the floor surface F.

  Further, since the ground contact surface 73 of the front stopper 72 is formed in a flat shape, a large ground contact area with the floor surface F can be secured, and the frictional force with the floor surface F can be increased.
